11 SEO Keyword Types to Boost Your Rankings (2025 Guide)

Digital   /  Jun 3, 2025

You’re developing something groundbreaking, but your audience can’t find you.

In life sciences, biotech, and pharma, even the most innovative solutions can get lost in a sea of competitors, long sales cycles, and complex buyer journeys. At Zool, we help science-led companies cut through the noise with SEO strategies built for how their audiences search.

These 11 keyword types are the foundation of smarter visibility, so your brand shows up when it matters most.

Short-Tail Keywords: Broaden Your Visibility

Broad terms capturing general industry interest.

• Examples: “gene therapy” and “clinical trials.”
• Why use them? High search volume increases visibility, informing your content and research strategies.
• Pro Tip: Complement these with long-tail keywords to maximise impact.

Long-Tail Keywords: Target Precise Industry Queries

Highly specific phrases capture users with clear intent.

• Examples: “CRISPR gene editing companies,” “phase 3 oncology trials Europe.”
• Why use them? Lower competition and higher conversions to attract specialised audience segments.

Branded Keywords: Safeguard Your Brand Visibility

Keywords that include your organisation’s name or products.

• Examples: “Pfizer COVID vaccine,” “Illumina sequencing platforms.”
• Why use them? Protect your digital space, maintain SERP dominance, and ensure competitors don’t redirect your hard-earned traffic.
• Pro Tip: Competitors can (and often do) bid on your branded terms in PPC to hijack high-intent traffic. Defend your brand by running paid ads on those keywords, pushing rivals down the page and keeping your brand in the spotlight.

Non-Branded Keywords: Expand Your Market Reach

General industry terms that attract users unfamiliar with your brand.

• Examples: “biotech consulting services,” “pharmaceutical cold chain logistics.”
• Why use them? Attract new potential customers, build awareness, and expand your audience.

Buyer Intent Keywords: Capture Purchase-Ready Prospects

Search terms signalling strong commercial intent.

• Examples: “best contract research organisation,” “purchase laboratory freezer.”
• Why use them? Drive immediate conversions from decision-makers ready to purchase.

Informational Keywords: Educate and Engage

Phrases focused on providing knowledge or solutions.

• Examples: “how does mRNA vaccine work,” “guidelines for FDA approval process.”
• Why use them? Establish authority, attract early-stage visitors, and build trust in your expertise.
• Pro Tip: Don’t stop at answering the question—guide the next step. Use clear CTAs (like downloadable resources or “speak to a specialist” prompts) to move top-of-funnel traffic into your pipeline. Informational keywords are perfect for starting relationships that evolve into real leads.

Navigational Keywords: Quickly Guide Users to You

Keywords your audience uses to access your site or service pages directly.

• Examples: “AbbVie investor relations,” “Thermo Fisher customer support.”
• Why use them? Help users easily find critical resources or pages specific to your company.

Transactional Keywords: Drive Specific User Actions

Action-oriented phrases to capture high-intent visitors.

• Examples: “download clinical research whitepaper,” “request biotech consultation.”
• Why use them? Optimise landing pages, improve lead generation and accelerate conversions.

Geo-Targeted Keywords: Dominate Local and Regional Markets

Localised keywords aimed at region-specific searches.

• Examples: “biotech companies in Boston,” “pharma distributors Europe.”
• Why use them? Strengthen your presence in key geographic areas, which is vital for local market penetration.

LSI (Related) Keywords: Improve Contextual Relevance

Semantically related phrases improve content depth and clarity for search engines.

• Examples: “genetic sequencing services” for “DNA sequencing,” “clinical research services” for “clinical trial management.”
• Why use them? Boost topic relevance and SEO rankings and attract broader organic traffic.
• Pro Tip: We use LSI keywords naturally in subheadings, image alt text, and FAQs to reinforce topical depth without keyword stuffing. This helps Google better understand your content’s context, and can unlock additional SERP features like “People Also Ask” and featured snippets.

Competitor Keywords: Stay Ahead of Industry Rivals

Keywords reveal competitors’ strategies and successful approaches.

• Why use them? Discover opportunities your competition misses, refine your strategy, and outperform rivals.
• How to find them: Tools like Ahrefs or Semrush help identify competitors’ strongest keywords.
